Frequently asked questions
How do I calculate sales tax?
Multiply the pre-tax price by the tax rate divided by 100. A $50 item at 8% tax: $50 x 0.08 = $4.00 tax, total $54.00. The Sales Tax Calculator handles this instantly for any price and rate, and it auto-detects your local currency.
Which US states have no sales tax?
Five states have no statewide sales tax: Alaska, Delaware, Montana, New Hampshire, and Oregon. Delaware, Montana, New Hampshire, and Oregon have no local taxes either. Alaska allows local municipalities to set their own sales tax, so many Alaskan cities do charge one.
Are these tax calculators free?
Yes, completely free. No registration, no usage limits, no premium tier. Every calculator runs entirely in your browser - nothing is sent to any server.
